(Fig. 5)
Material examined. Female (UPLG.19.64), Philippines, Luzon Island, Laguna, Paete, Barangay Ilaya, UP Land Grant, N14.39612, E121.54702, 437.5± 5.6 m.a.s.l., 1105 hours, 7 September 2019, on foliage, coll. M. K. Tan, J.
B. Baroga-Barbecho, C. C. Lucañas and S. A. Yap, pinned (ZRC).
Remarks. Although this specimen was collected from the same locality as M. lagunan. sp., this female specimen clearly differs in the darker colouration (particularly the lateral parts and legs). Since sexual dimorphism is not commonly observed in Mnesibulus, we consider this as a tentative species unique from M. lagunan. sp. until more materials are available.
Measurements (in mm). Female: BL = 12.2; PL = 2.0; PW = 2.8; TL = 12.2; HWT = 3.9; HFL = 8.1; HTL = 7.3; OL = 4.2.
